To all whom it may concern. 7

Be it known that I, OSCAR A. DOVER, a citizen of the United States,residin -at Gastonia, in the county of Gaston and ate of North Carolina,have invented certain new and useful Improvements in Lubricating Meansfor Spinning-Rings, of which the following is a specificatio Myinvention relates to the twister frames of spinning machines and moreparticularly to the construction of an improved spinning rin for use inconnection therewith.

he object of the invention is to provide means for conveniently andeffectively supplying oil to lubricate such spinning ring, so as tocause the traveler to run freely and smoothly thereon without unduefriction.

More specifically, I contemplate roviding ti my improvedlubricatingmeans, so that twister frames in common use may be equippedwith my invention, without the necessity of buy- .1n new rings or partsof any kinds.

11 order that my invention may be readily understood, reference is hadto the accom-' panying drawings, ,forming part of this specification andin which- Figure 1 is a fragmentary plan view of a portion of a ringrail showing a spinnin ring thereon provided with my improve lubricatinmeans;

Fig. 2 1s a vertical section substantially on the line 2-2 of Fig. 1,and

Fig. 3 is an enlarge fragmentary section on the same line.

Referring to the drawings in detail, 1 designates the usual rin rail on'which the rmgs are supported. e ring itself, which is smooth andimperforate throughout, and has a vertical outer wall, is designated bythe reference numeral 5, and is provided with a peripheral flan e 2constituting a holder. This flange is ormed with diametrically opposedslotted lugs 3, through which set screws 4; pass. screws the ring andnge may be adjustably secured to the ringrail.

6 designates the traveler which may be of any usualor desired form.

In the up or surface of the holder or flange 2, I orm an annular oilreceivin groove 7, which surrounds the ring 5, an at one or more pointsI provide ducts 8 extending downwardly from the groove 7 Bf? means ofthese set the flange 2 to the lower side there throng? of. shown in ig.3, these ducts 8 are preferably inclined and terminate at their lowerend adjacent the outer vertical wall of the ring 5.

By virtue of this construction, it will be apparent that oil placed inthe groove 7 will flow downwardly through the ducts 8 from whence itwill find its way over and around the outer wall and lower edge of thering 5. Such oil is uniformly distributed around the ring by themovement of the traveler.

The ring 5 is usually constructed of hardened steel, while the flange orholder 2 may be formed of brass or the like, and it will be noted thatwith my improved construction, it is not necessary to bore or drillthrough the ring itself in order to supply oil to the lower edgethereof, as in arrangements heretofore proposed, oil is delivered to theouter surface of the ring and finds its way downwardly along the same.

It will thus be seen that I have provided a simple and effectivearrangement for distributing oil to spinning rings, my im rovement beingsuch that it can be readi y applied to existing rings now in use, and itis thought that the many advantages of my invention will be apparentwithout further discussion.

What I claim is:

1. The combination with an imperfo'rate spinning ring, of a supportingmember therefor, said member having in its upper face an annular oilgroove surrounding the ring, and vprovided with ducts extending throughitself so asv to conduct oil to the lower edge of said ring.

2. The combination with a spinning ring having a vertical outer wall, ofa supporting member for said ring, said member having in its upper facean annular oil groove and provided with ducts extending downwardlythrough itself and terminating adjacent the vertical wall of said ring,whereby oil is conducted from said groove to saidring, and flows downand over the outer surface thereof.

In testimony whereof I aflix my signature.
